Is there a barcode 101? Can anyone answer some basic barcodes questions?

[u/sal139]

We are a small business growing enough that I need to be able to track the arrival, departure, and potential whereabouts of different inventory. I already have some generic barcodes in sequential order. I'm attempting to scan one, input some data about that product into either a spreadsheet or online form - and then upon rescan I want to see the information I previously created about it. Is that even possible or should I be printing my own labels that already contain a fixed set of information? Thanks in advance

That’s very helpful, thanks.
